Themember 10 carries two winding" posts 14 It is another object of the invention to imand 15, they being-mounted adjacent the ends prove the construction of t t p holding mea of said member 10, as best illustrated in Figures and thereby eat y aoil t e thr ad or e 1 to 3- inclusive of the drawings. As best illusthreading Ofthe ach n tratedin Figure 4, the winding post 14 is ad- 50 It is still another-object'of the invention to projustably mounted in an elongated slot 15' in the vide a novel mechanism whereby the severing member 10 by means of a nut 16 threaded upon of the finished hank or skein from the strip the winding post 14 and adapted to clamp the from which it is formed is performed after the member 10 between itself and a shoulder 17 prestrip has been re-threaded into the winding'head, sentedby anenlarged portion 18 of the winding #5 thus greatly facilitating the re-threading of the post.

The opposite end of the member 10 may be twisted as at 19 to present a flat face 20 substantially at right angles to the main body portion of the member 10, and as best illustrated in Figure 6, the winding post 15 is mounted as at 21, on this flat face 20, for pivotal movement about a stud or the like 22 which passes through a lug or projection 23 extending from the edge of the winding post 15. For rocking the winding post 15 about its pivotal point 21, a handle 24 may be provided, and a spring 25 secured at one of its ends to the winding post 15, as at 26 g and at its other end to a stationary point 27,

formed, and it alsoincludes the severing means by which the formed'hank or skein is cut or severed from the strip.

- The'specific construction of this winding post 15 is best illustrated inz-Figures 6 and 7 and,

by reference to said figures, it will be seen that the main body portion of the Winding post 15 is cut out as at 33. Pivotally mounted in this cut out portion 33,-as at34, there is a clamping jaw or member 35 reduced as at 36, to receive about its pivotal point 34, to the position illustrated in broken lines in Figure 7'. To-insure engagement of the'nose 37 of the'clamp 35 with the cam face 38, a spring 44 is interposedbetween the'clamp 35 and the 'right angular extension 45 of a bracket-46 secured as at 47 to the winding post 15.

In addition to forming a clamp for the ribbon strip. the member 35 acts in conjunctionwith an edge 50 undercut as at 5l'to sever the formed hank or skein from the strip from which it is 1 with a groove 61, .and a spring tension finger 62 overlies said groove as shown in Figures 1. to 3.

formed, and this severing action is completed simultaneously with the clamping operation-in a manner hereinafter described. I I. V 1

.The:de,vice operates in .the following manner: The ribbon strip from which the hank orskein in formed-is designated 55, and it is supplied from asuitable roll, spool or in any other desired manner over a suitable guide 60. This guide 60', preferably consists of a circular member formed Passing .through the groove 61 and arranged di ametrically opposite to the ribbon strip 55, there is a strip 63 of paper, preferably wider than said ribbon strip, which not only forms a protection forthe latter strip, but also provides a support for the various loops of the hank or skein between which-the paper strip is interposed, whereby said loops will have a certain amount of rigidity im-- parted thereto and be better maintained in aligned positions relative to .each other.

In Figure 1, the ribbon strip 55 andthe paper strip 63 are shown as attached to the winding post 15in position to start the formation of the hank or skein. This attachment of the strips 55 and 63 to the winding post 15 is accomplished by grasping the handle portion 24, and rocking the winding post 15 around its pivotal point 21. This movement of the winding post 15 causes the cam face 38 to move the clamp 35 to the broken line position in Figure 7, and permits of the insertion of the ends of the two strips between the clamp 35 and the co-operating part of the winding post 15. If now the handle 24 be released, the parts return to the position in which they are shown in Figure 1 and the hank or skein forming operation is ready to start.

The head is now rotated to form the desired number of loops about the winding pins 14 and 15 after which a clip 65 of stiff cardboard, metal or other suitable'material is passed around'the body portion of the hank or skein intermediate said pins to maintain the formation illustrated in Figure 3.

After the hank or skein has been formed, it is stripped from the head in the following mannerj-The operative grips, with one hand; the strips 55 and 63, and with the other hand, grasps the handle 24 and rocks the winding pin 15 around its pivotal point. This actionmoves the clamp 3'5't-o release the ends of said'stripswhich were gripped before the coils of the hank were formed, and also moves the winding post 15 from within one of the loops of the hank or skein, leaving the'same hanging upon the winding post 14.

The handle 24 is maintained in 'its'rocked position until the uncut portions of the strips which will form the outer end ofthe hank are again pa'ssed'between the clamp'35 and the adjacent portion of the winding-post 15, after which the handle 24-isreleased so as toreturn to normal position, thereby'clamping the two strips 55 and 63 to said winding post.

the clamp 35 moves to clamping position 'its'edge'65, in passing by the undercut e'dge 5O,

produces a shearing action which severs "the formed hank or skein from the strips simultane ousl-y with the clamping of the free ends of the latter produced by the cutting operation, after which the hank or skein is removed from the winding pin'14 and the aforementioned; cycle of operation completed-to form ano'therhank'or skein, To insure a complete shearing action, the

edge 65 of the clamp 35 is maintained resilient- 1'.

ly in engagement with (he under cut edge 50 of the winding pin'l5 by a flat spring mounted in the cut out portion 33 of the winding post Y 15, and this spring has its free'end '71' engaging the clamp 35 as bestshown in Figure 6.

By ihreading'the winding post 15 before the hank or skein is severed from the strips from which it is formed, the threading operation is greatly facilitated since the operation'is ,more easily carried out in this manner than in the heretofore commonly threading in the free end of a strip. By making the hank or skein severing operation's'imultaneous with'the clamping operation, the necessity. of employing separate hand shears or the like is obviated, and the hank or skeinsev'ering operation is greatly facilitated.

From the foregoing, itwillbe apparent that the present invention provides a novel"mecha-' nism by which the formation of hanks or skeins of ribbon may be carried out with greater facility than is possible-with such mechanisms as here tofore constructed-,and that the device of'the present invention is very simple in construction employed manner of Having thus described the invention, what is claimed is: V V
